RANCHO CUCAMONGA, CA — STV announces the completion of the upgraded Moreno Valley/March Field Metrolink Station Improvement Project on the 91/Perris Valley Line (PVL). STV served as the lead consultant for the $38 million station upgrades, providing project management, design, construction support, and environmental clearance for the Riverside County Transportation Commission (RCTC) and Southern California Regional Rail Authority (Metrolink).
The upgraded station is a critical step toward expanding commuter rail service in one of the fastest-growing regions of the country. Upgrades include the addition of a second platform and extending the original platform from 510 to 680 feet to accommodate Metrolink’s standard eight-car train length — improving capacity from six-car train length as well as operational flexibility for peak-period and reverse-commute service. The project also included the rehabilitation of 2.7 miles of adjacent track to enable bi-directional service through the station as the first phase of a planned 9-mile double-track corridor designed to enhance long-term service reliability and increase train frequency within Riverside County.
“By expanding capacity and improving reliability in Moreno Valley, the upgrades help ease commute times and connect residents to opportunity and supports cleaner, more sustainable growth,” said Andy Sokol, Vice President and Engineering Director at STV. “It’s been an honor to partner with RCTC and Metrolink on a project that will help unlock the Perris Valley Line’s full potential, spurring smarter growth and better mobility across the region.”
Moreno Valley residents face some of the longest daily commute times in the country and the Southern California region as a whole, spending an average of an hour and 10 minutes commuting each day. The Riverside-San Bernardino metro area continues to grow, with a projected population increase by 57 percent to 7.4 million people by 2060. By expanding commuter rail options and shifting more trips from cars to rail travel, the project supports RCTC’s goals to ease congestion on Interstate 215, improve regional economic connectivity, and improve air quality. The upgrades are also part of Metrolink’s Southern California Optimized Rail Expansion program, which enhances the Metrolink system in preparation for the 2028 Olympics and Paralympics Games in Los Angeles, California.
STV has played a central role in the development of the 91/Perris Valley Line since its inception, working alongside Metrolink and the RCTC to deliver the 24-mile PVL extension that opened in 2016, including the original design of the Moreno Valley/March Field Station and three others along the route. STV also provided design services for RCTC’s Riverside Downtown Security Operations Control Center, which oversees the Metrolink system in Riverside County.
